Abstract

Denne oppfinnelsen angår en fremgangsmåte for å forbedre hørbarheten av en kringkastings-styrekanal for en basestasjon (BTS1 til BTS3) i et radiosystem hvor sender/mottaker-enheter er delt etter TDMA/FDMA-prinsip- pet i kanaler, hvor basestasjonene (BTS1 til BTS3) omfat- ter midler for å etablere en radioforbindelse til radio- enheter (MSI, MS2) i deres radio-dekningsområde, og mid- ler for å sende en kringkastings-styrekanal, hvorved systemet innbefatter minst to basestasjoner (BTS1 til BTS3) som er innrettet for å sende kringkastingsstyre- kanalen ved å benytte samme forutbestemte frekvenskanal (Fl). For å redusere interferens justeres sendeeffekten for basestasjonens forutbestemte frekvenskanal (Fl) til en lavere verdi i de tidsluker hvor kringkastings- styrekanalen ikke sendes, enn i den eller de tidsluker hvor kringkastings-styrekanalen sendes. Oppfinnelsen angår også et celledelt radiosystem.This invention relates to a method for improving the audibility of a broadcast control channel for a base station (BTS1 to BTS3) in a radio system where transmitter / receiver units are divided according to the TDMA / FDMA principle in channels, wherein the base stations (BTS1 to BTS3) ) comprises means for establishing a radio connection to radio devices (MSI, MS2) in their radio coverage area, and means for transmitting an broadcast control channel, the system including at least two base stations (BTS1 to BTS3) which are adapted to transmit the broadcast control channel using the same predetermined frequency channel (F1). To reduce interference, the transmit power of the base station's predetermined frequency channel (F1) is adjusted to a lower value in the time slots where the broadcast control channel is not transmitted than in the time slot (s) where the broadcast control channel is transmitted. The invention also relates to a cellular radio system.
